HEAD FOR VENTILA'IING OR HEATING FLUES.

Specification of Application filed April 24,

To all whom it may concern:

Be it known that I, Josnrn Gnomes, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Heads for Ventilating or Heating Flues, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

The present invention relates to heads for ventilating or heating fines and an object of the same is to provide a construction in which the head is provided with its own closure or valve which preferably is removable to the end that the head may be used with a valved register if desired.

Another object of the invention is to provide an operating mechanism for a swinging valve, constructed to hold such valve in diiierent'positions and being simple in operation and inexpensive to manufacture.

To these and other ends the invention consists in certain parts and combinations of parts, all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings: Figure 1 is a front view of the head showing it in position in the wall with the valve in closed position; Fig. 2 is an enlarged section on the line a d of Fig. 1 showing, by full lines, the valve in closed position and, by dotted lines, in open position; Fig. 3 is an enlarged view of the operating mechanism of the valve, showing the latter in open position; Fig. 4t is a vertical section of the valve operating mechanism with the valve closed; Fig. 5 is a section on the line b--?) Fig. 3; and Fig. 6 is a perspective view of the valve operating mechanism.

In heating and ventilating systems now in use and employing flues, it is customary to provide, at the extremities of the tines, heads opening into the room or comparttrance to such heads being controlled by registers provided with valves. WVith such an arrangement, when the register valves are closed, an escape is provided between the register and the head as this is not a tight joint. This is disadvantageous in heating systems in that the heat escapes between the register and the head and discolors the wall in proximity to and surrounding the register. Furthermore when the valve is carried by the register, the

usual head collar, which is surrounded by the laths, becomes hot thus charring the laths so that there are possibilities of fires. This invention overcomes these defects by closing the valve within the head and by causing a circulation of air within the collar when the valve is closed.

According to the illustrated embodiment, the head formed with openings, one serving as the inlet and the other as the outlet, depending upon whether the head is used in a (Clitllttiliflg or in a heating system. Preferably, these openings are at right angles, the opening 1 being coextensive in area with the cross sectional area of the head, while the other opening is surrounded on its exterior by a collar 2 which serves as an abutment for the laths 23 of the wall. The walls ot the head may be double and have their two parts spaced from each other and separated by a filler such as asbestos in board form or otherwise. The opening which surrounds the collar is not so wide nor is it so long as the head and therefore a seat is provided about the said opening and within the head for engagement by a valve member l. This valve-member is preterably in the form of a plate hinged at 5 to the end of the head opposite the opening 1, so that its swinging end lies in proximity to the said opening. The valve member is substantially as wide as the interior of the head in order that, when it is thrown to the position shown in dotted lines Fig. 2, its free end engages the rear wall of the head and, in this way, the valve acts as a deflector for directing air or the like from one opening in the head to the other. As the pivot is arranged within the head and in proximity to the end of the casing opposite the opening 1, the full area of the opening, which is surrounded by the collar 2, is obtained.

For operating the valve 4-, there may be provided a slide 6 which, preferably, has two faces 7 parallel with each other but at oblique angles to the line of movement of the slide. This slide may be supported on a way 8 formed on the front face of the depending bracket 9, the inclined :tace of the slide projecting from opposite sides of the b 'acket to cooperate with shoulders 10 which, in this instance, are in the form of arms extending forwardly from the valve member 4t and connected to their inner ends by a piece 5 forming with the arms a U- at the end opposite the opening 1.

shaped member Which projects through openings in the valve 4. .The slide may be, actuated in any suitable mannerbut, in this instance, there is employed a lever 12 ,pivoted at 13 and having slots 14 the walls of which cooperate with the pins 15 projecting forwardly from theslide 6. Upon the opposite side of the pivot, the lever l2 hasan operating hand piece 16 by which it "is" manipulated. The head is so constructed that the valve and its operating parts may be removed in order that the head may be employed with any 1 special 'make of register when desired. To this end, the iblock 1 is bolted ate the inner side of :the collar '2 This block is grooved :on :its inner face and, in its :groove iis arranged "an anchor :member 18 to which the --valve 4 is lpivote dzat 5., said anchor member having its outer :end turned laterally .at 19 to cooperate with the outer tacezoif the collar 2. Also sfitted in the recess of :the block 117 is a lateral extension QO on the depending bracket :9, this extension filling up the pocket or =recess and holding the anchor piece '18 against withdrawal. .A spring latch 21 may cooperate with the depending bracket i9 in :order to hold the extension on said fbrac'ket within the recess of the block 17. it is sapparent- 'that, when the latch is moved to tree the bracket 9 and the extension 20, these -parts may be withdrawn from the b'lock 17, after which the anchoring piece 18 may drop so that the latter may be Withdrawn. With this Withdrawal, the va l've 4 is unsupported and may be removed through the opening which is surrounded by :the "collar 2. A strip 22 mayconnect the front and rear walls "of the head to prevent the dropping of the valve 'through 'theopening 1 into the flue system.

When the head is installed in place, the laths 23, which are secured to'the studs 24 of the building wall, project over the :front wall of the head into abutment with the collar 2, as is clearly shown in Fig. 1. In the closed posit-ion of the valve, the operating mechanism is in the position shown in Fig. 1:-while the-open position of the valveoperating mechanism is shown in Fig. 8, the lever 16 being shifted from one extreme position to the other and, during this vmovement, causing the cam faces 7 to cooperate with the shoulders 10 and efi ecti'ng the swinging movemento'tf the valve 4.

A head for heating or ventilating systems constructed in accordance with this inven tion, is provided With its own valve which is so mounted as to give the full "opening therethrough "Without any retarding action. The valve, when closed, acts to prevent the escape of heated air which may discolor the wall about the head and the *heat is con fined within the head proper where the Walls are double being excluded train the The valve and its operating mechanism may be removed in'order that the head may 'ibe 7 used with .an ordinary register, which is otherwise "unnecessary.
